摘要
目的探讨多层螺旋CT(MSCT)对肠扭转的诊断价值。方法收集急腹症MSCT双期增强扫描病例80例,其中10例患者图像经多平面重组(MPR)及肠系膜血管最大密度投影(MIP)处理,诊断为肠扭转。结果MSCT诊断10例肠扭转,主要征象有肠系膜血管“漩涡征”10例,肠管“漩涡征”5例,靶环征或双晕征5例,肠系膜上动脉、静脉(SMA、SMV)换位征3例,鸟喙征4例,SMV血栓形成2例,腹水征10例。诊断均经手术证实。结论MSCT双期增强扫描及多平面重组(MPR)与肠系膜血管最大密度投影(MIP)对肠扭转的诊断有重要价值。
Objective： To investigate the diagnostic value of MSCT in intestinal volvulus so as to improve the accuracy diagnosing rate. Methods： 80 cases with acute abdomen pain underwent two phases enhencement scan using MSCT, among which 10 cases were diagnosed in intestinal volvulus, using multiplanar reformation （MPR） and mesenteric vessels maximum intensity projection（MIP）. Results： All the 10 cases were diagnosed accurately, the main signs were＂ whirl pool＂of mesenteric vessels（ 10 cases） ,＂ whirl pool＂of intestine （5 cases）, ＂target sign＂ or ＂double-halo sign＂（5 cases）,exchange of SMA and SMV （3 cases）, ＂beak sign＂（4 cases）, superior mesenteric venous thrombosis （2 cases）,abdominal tluid（ 10 cases）. Diagnosis were right proved by operation. Conclusion： Artery and vein enhancement scan of MSCT and reconstruction of mesenteric vessles（ MPR and MIP） have great value in diagnosing intestinal volvulus.
